scripture: add a dedicated non-Psalm scripture store, migrate pure-scripture readings

Adds src/scripture/ (types.ts, index.ts), a verse-addressable store mirroring
psalter/index.ts's own pattern exactly -- getScriptureVerses(book, chapter,
range) -- for non-Psalm scripture (Wisdom, Canticles, Ezekiel, Acts, Joel,
etc.). Kept as its own module, not folded into the Psalter, per 2026-08
discussion ("the psalms kind of work differently even if the logic is the
same, they do need their own store").

Octave readings can now declare `passages: [{ book, chapter, verses }]`
instead of embedding text -- each entry becomes its own paragraph, letting a
reading built from several verse ranges keep its original paragraph breaks.
getOctaveReading resolves either shape (embedded text or passages) into the
same OctaveReadingText callers already expect, so nothing downstream needs
to know which was used. Scope, per discussion: only readings that are
Scripture start to finish get this treatment -- prose that merely quotes a
verse or two (most of the patristic sermons pulled so far) keeps its
quotations embedded inline, as before.

Migrates the 9 already-committed octave readings that are pure Scripture
(Wisdom 4:7-20, Canticles 1 and 8, seven different Ezekiel excerpts across
All Saints' octave -- one of which, day 7, genuinely spans two chapters --
and Acts 19/Joel 2 for Pentecost's octave) to the new passages notation,
verified to resolve to character-identical text as before.

-    Lesson from the book of Ezekiel Ezek 1:1-3 1 Now it came to pass in the thirtieth year, in the fourth month, on the fifth day of the month, when I was in the midst of the captives by the river Chobar, the heavens were opened, and I saw the visions of God. 2 On the fifth day of the month, the same was the fifth year of the captivity of king Joachin, 3 The word of the Lord came to Ezechiel the priest the son of Buzi in the land of the Chaldeans, by the river Chobar: and the hand of the Lord was there upon him.

-    Ezek 1:4-6 4 And I saw, and behold a whirlwind came out of the north: and a great cloud, and a fire infolding it, and brightness was about it: and out of the midst thereof, that is, out of the midst of the fire, as it were the resemblance of amber. 5 And in the midst thereof the likeness of four living creatures: and this was their appearance: there was the likeness of a man in them. 6 Every one had four faces, and every one four wings.

-    Ezek 1:7-9 7 Their feet were straight feet, and the sole of their foot was like the sole of a calf's foot, and they sparkled like the appearance of glowing brass. 8 And they had the hands of a man under their wings on their four sides: and they had faces, and wings on the four sides, 9 And the wings of one were joined to the wings of another. They turned not when they went: but every one went straight forward.
